Qu'est-ce que le nickel ? Ferronickel ? Fonte au nickel ? Alliages \u00e0 base de nickel ?<\/strong><\/h2>\n\n\n\n

A travers cet article, KAYSUNS, le fournisseur de raccords de tuyauterie en acier inoxydable<\/a> vous pr\u00e9sentera ce que sont le nickel, le nickel fer, la fonte nickel et les alliages \u00e0 base de nickel, leurs caract\u00e9ristiques, leurs utilisations, etc.<\/p>\n\n\n\n

Nickel<\/strong><\/p>\n\n\n

Le nickel est un \u00e9l\u00e9ment de m\u00e9tal de transition, symbole d'\u00e9l\u00e9ment Ni, situ\u00e9 dans le groupe VIII de la quatri\u00e8me p\u00e9riode, num\u00e9ro atomique 28. Le nickel est principalement utilis\u00e9 dans les domaines de l'acier, des alliages \u00e0 base de nickel, de la galvanisation et des batteries. Il est largement utilis\u00e9 dans diverses industries de fabrication militaire telles que les avions et les radars, dans la fabrication de machines civiles et dans les industries de galvanisation. Le nickel est l'une des principales mati\u00e8res premi\u00e8res de l'acier inoxydable. La consommation de nickel dans l'industrie chinoise de l'acier inoxydable repr\u00e9sente plus de 80% de la consommation primaire de nickel et plus de 2\/3 au niveau mondial.<\/p>\n\n\n\n

Ferronickel<\/strong><\/p>\n\n\n\n

Alliage de fer et de nickel avec une teneur en nickel de 15% ou plus (fraction massique) et inf\u00e9rieure \u00e0 80% (fraction massique) obtenu \u00e0 partir de minerais oxyd\u00e9s ou d'autres mat\u00e9riaux contenant du nickel. Selon la norme nationale GB\/T25049-2010, le ferronickel peut \u00eatre divis\u00e9 en cinq cat\u00e9gories : ferronickel \u00e0 faible teneur en carbone, ferronickel \u00e0 faible teneur en carbone et faible teneur en phosphore, ferronickel \u00e0 teneur moyenne en carbone, ferronickel \u00e0 teneur moyenne en carbone et faible teneur en phosphore et ferronickel \u00e0 haute teneur en carbone. .<\/p>\n\n\n\n

Fonte au nickel<\/strong><\/p>\n\n\n

\n
\"fonte
fonte nickel\u00e9e<\/figcaption><\/figure>\n<\/div>\n\n\n

La teneur en nickel de la fonte brute de nickel est inf\u00e9rieure \u00e0 15%. En g\u00e9n\u00e9ral, selon la teneur en nickel de la fonte brute de nickel, on peut la diviser en fonte brute de nickel de qualit\u00e9 sup\u00e9rieure (10% et plus), fonte brute de nickel de qualit\u00e9 moyenne (4-9%) et fonte brute de nickel de qualit\u00e9 inf\u00e9rieure. La fonte brute de nickel est principalement fondue dans des fours \u00e0 arc submerg\u00e9 et des hauts fourneaux. En g\u00e9n\u00e9ral, les fours \u00e0 arc submerg\u00e9 produisent de la fonte brute de nickel de haute qualit\u00e9, et les hauts fourneaux, de la fonte brute de nickel de basse qualit\u00e9. La fonte brute de nickel est une source importante de mati\u00e8re premi\u00e8re de nickel pour l'acier inoxydable.<\/p>\n\n\n\n

Alliage \u00e0 base de nickel<\/strong><\/p>\n\n\n\n

Un alliage \u00e0 base de nickel est un alliage \u00e0 base de nickel (avec une teneur en nickel \u226550%) et contenant des \u00e9l\u00e9ments tels que Cr, Mo, Cu, Al, Ti et Nb. En fonction des performances principales, il est divis\u00e9 en alliages r\u00e9sistants \u00e0 la chaleur \u00e0 base de nickel, en alliages r\u00e9sistants \u00e0 la corrosion \u00e0 base de nickel, en alliages r\u00e9sistants \u00e0 l'usure \u00e0 base de nickel, en alliages de pr\u00e9cision \u00e0 base de nickel et en alliages \u00e0 m\u00e9moire de forme \u00e0 base de nickel. Par exemple, Inconel 690<\/a>, Hatselloy C-276<\/a>, Haynes 242, Monel 400<\/a>, Incoloy800<\/a> et autres alliage \u00e0 base de nickel<\/a> marques.<\/p>","protected":false},"featured_media":3541,"template":"","categories":[186],"tags":[],"class_list":["post-6246","blog","type-blog","status-publish","has-post-thumbnail","hentry","category-stainless-steel-knowledge"],"yoast_head":"\nDefinition: Nickel, Ferronickel, Nickel Pig Iron, Nickel-based Alloys<\/title>\n<meta name=\"description\" content=\"What is Nickel?
